merge: record the "other" node in merge state

We need to record the merge we were merging with. This solve multiple
bug with resolve when dropping the second parent after a merge. This
happen a lot when doing special merge (overriding the ancestor).
Backout, shelve, rebase, etc. can takes advantage of it.

This changeset just add the information in the merge state. We'll use it in the
resolve process in a later changeset.
